Introduction
BS-1008 adopts semi-apochromatic parallel optical imaging system, and uses advanced multi-layer coating technology, which perfectly correct the imaging on the edge of field of view, get high-resolution and high contrast images, and naturally restore the true colors of observed objects.
For applications that require different magnification, Auxiliary Lens or infinity objectives with different magnification can be attached to the front end of the Middle Zoom Module.
For application that require different sensor size, TV Lens with different magnification can be attached to the back end of the Middle Zoom Module.
The basic module of BS-1008 is BS-1008A(does not have stop) and BS-1008B(has stop at main magnification), it has 0.7X to 5.6X zoom range and 1:8 zoom ratio. It is a high-quality precision Monocular Zoom Objective that provides high resolution and large depth of field.

| Remarks |
When using coaxial lighting, low magnification may produce vignetting.
When using infinity objectives as Auxiliary Lens Module (adapter available), the PMAG, FOV and NA of the BS-1008 depends on the parameters of the objectives. |
|
WD: Working Distance;
PMAG: Primary Magnification;
FOV: Field of View in the Object side;
NA: Numerical Aperture;
Note: Infinity corrected objectives limit system's usable zoom range due to uneven illumination. Max sensor format is 2/3".
